Westvleteren 12, does it mean that's 12%?
No, it's 10.2% ABV.
The Belgian degree system, which describes the
density of the beer, is only loosely related to the formalised notion of
gravity.
Though not particularly accurate (because every bottle is unique), it is still a useful way of differentiating products in a product line: 6, 8, 10 and 12 are the usual numbers.
The thing you
can say with some certainty is that higher the number, the more time has been spent brewing the beer and the more alcoholic it tends to be, though the respective characters of each degree in the same product line can be wildly different.
Some examples of these differences:
As a bog standard brew, Maredsous 6 on tap is lovely, whilst the 10 can be a step too close to aftershave for me.
Likewise I prefer a Rochefort 8 to a 10. The 10 is a bit oversweet and rooty for my tastes, though my other half prefers it to the 8, which I like because it's smokier and goes well in cooking.
These are quite apart from the other "scales" used: dubbels, tripels and quadrupels - which usually describe the doses of malt in the brew - and blue, red, etc, which is mostly just brandspeak for dubbel, tripel and quadrupel.
Try them all, is my advice. It's more fun that way!
